On-Chip OTP (OCOTP) Controller
20.1 OCOTP Overview
The on-chip OTP controller (OCOTP) provides the following functions:
The OCOTP is connected to the APBH system peripheral bus and is accessible through the
ARM core. Read accesses can be performed at the maximum HCLK frequency.
Programming/writes can be performed at 24 MHz. There are two security encription keys
that are supplied to the DCP block. The first is the Crypto key which is made up of the 128
bits from registers HW_OCOTP_CRYPTO0 through HW_OCOTP_CRYPTO3. The least
significant bits are in register 0. The Unique key is made up of the 64 bits from registers
HW_OCOTP_OPS2 and HW_OCOTP_UN2. The least significant bits are contained in the
OPS2 register. The system diagram for the OCOTP is shown below.
